[0002] Flame-retardant solid woven conveyor belts for bucket wheel excavators are key components developed to meet the demands of large bulk cargo ports, thermal power plants, and mining industries for efficient, safe, and continuous operations. They are made by impregnating an integral woven belt core with PVC or PVG paste, resulting in a robust structure. With their extremely high tear resistance and excellent flame-retardant safety, they are widely used in bucket wheel stacker-reclaimers for the storage and retrieving of flammable and explosive bulk materials such as coal and ore, effectively ensuring the safe production and continuous operation of large industrial sites.

[0003] In existing bucket wheel excavator conveyor belt technology, the cooling process is often inadequate. Some equipment lacks an effective circulating cooling system and relies solely on natural heat dissipation. During long-term high-load operation, the large amount of heat generated by friction between the drive rollers and the conveyor belt is difficult to dissipate, leading to rapid aging and deformation of the conveyor belt, and even causing safety hazards. Therefore, a flame-retardant solid woven conveyor belt for bucket wheel excavators has been developed. Utility Model Content

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This embodiment of the present invention provides a flame-retardant solid woven conveyor belt for bucket wheel excavators, comprising: The frame 101 includes casters 102 fixedly mounted on the surface of the frame 101, a crossbeam 103 welded to the surface of the frame 101, a lifting assembly 104 fixedly mounted on the surface of the crossbeam 103, a frame 105 fixedly connected to the end of the lifting assembly 104, a mounting plate 106 disposed on the surface of the frame 105, a circulation assembly 107 fixedly connected to the surface of the mounting plate 106, a conveyor belt 108 sleeved on the surface of the circulation assembly 107, and an auxiliary assembly 109 movably connected to the inner wall of the frame 105. The circulation assembly 107 includes a storage tank 107a fixedly mounted on the surface of the mounting plate 106, a water pump 107b fixedly connected to the surface of the storage tank 107a, a three-way pipe 107c fixedly connected to the outlet of the water pump 107b, a delivery pipe 107d fixedly connected to both ends of the three-way pipe 107c, a drive roller 107e rotatably connected to the inner wall of the frame 105, a rotary joint 107f snapped onto both ends of the drive roller 107e, a spiral guide vane 107g disposed in the inner cavity of the drive roller 107e, the circulation assembly 107 also includes an outlet pipe 107h fixedly connected to the end of the rotary joint 107f, and a heat exchanger 107i fixedly mounted on the surface of the mounting plate 106.

[0019] The mounting plate 106 is fixedly installed at the middle position of the bottom of the frame 105, and the conveyor belt 108 is sleeved on the surface of the drive roller 107e and the idler roller 109a. The surface of the conveyor belt 108 is provided with a V-shaped groove.

[0020] Specifically, the outlet pipe 107h is fixedly connected to both ends of the three-way pipe 107c, the three-way pipe 107c is snapped into the side wall of the heat exchanger 107i, and the heat exchanger 107i is fixedly connected to the side wall of the storage tank 107a.

[0021] The drive rollers 107e are respectively set at both ends of the frame 105. Driven by a motor, they can draw coolant from the storage tank 107a and deliver it to the subsequent pipeline. The three-way pipe 107c is connected to the outlet of the water pump 107b, which diverts the coolant to the delivery pipes 107d at both ends. The rotary joints 107f snapped at both ends of the drive rollers 107e not only ensure the flexible rotation of the drive rollers 107e, but also realize the sealed transmission of coolant. The spiral guide vanes 107g set in the inner cavity of the drive rollers 107e can guide the coolant to flow evenly inside the drive rollers 107e and carry away heat. The outlet pipe 107h is connected to the end of the rotary joint 107f and delivers the coolant to the three-way pipe 107c to form a circulation loop. The heat exchanger 107i is fixedly installed on the surface of the mounting plate 106 and snapped with the three-way pipe 107c, which can exchange heat with the circulating coolant and reduce the coolant temperature.

[0022] Furthermore, the lifting assembly 104 includes a first shaft block 103a fixedly installed on the surface of the crossbeam 103, a connecting block 103b movably connected to the inner wall of the first shaft block 103a, a second shaft block 103c fixedly installed on the surface of the crossbeam 103, a support plate 103d movably connected to the inner wall of the second shaft block 103c, a cylinder 103e disposed on the surface of the support plate 103d, and a third shaft block 103f fixedly connected to the output end of the cylinder 103e.

[0023] The connecting block 103b is movably connected to the inner wall of the third shaft block 103f. The connecting block 103b is fixedly installed at the four corners of the bottom of the frame 105. The cylinder 103e serves as a power source, and the third shaft block 103f connected to the output end can precisely control the lifting height of the frame 105 through cooperation with the connecting block 103b.

[0024] Preferably, the auxiliary component 109 includes a roller 109a rotatably connected to the inner wall of the frame 105, and heat dissipation fins 109b formed on the surface of the roller 109a.

[0025] It should be noted that the heat dissipation fins 109b are spirally arranged on the surface of the idler roller 109a. When the idler roller 109a rotates normally, the fins can effectively agitate the air and quickly dissipate the heat generated by the contact between the conveyor belt 108 and the idler roller 109a.

[0026] In operation, the height of the frame 105 is adjusted by driving cylinder 103e to position the conveyor belt 108 at a suitable conveying angle. Water pump 107b is then activated, drawing coolant from storage tank 107a. After being pressurized by pump 107b, the coolant is diverted through three-way pipe 107c to delivery pipe 107d, and then enters the inner cavity of drive roller 107e through rotary joint 107f. Under the action of spiral guide vanes 107g, the coolant flows evenly inside drive roller 107e, carrying away the heat generated by friction between drive roller 107e and conveyor belt 108. The coolant, having absorbed heat, returns to three-way pipe 107c through outlet pipe 107h. Through heat exchange with heat exchanger 107i, its temperature is reduced before flowing back to storage tank 107a. When idler roller 109a rotates normally, the fins effectively agitate the air, rapidly dissipating the heat generated by the contact between conveyor belt 108 and idler roller 109a.

[0027] In summary, the circulation component 107, through the circulation of coolant and heat exchange in the heat exchanger 107i, can quickly reduce the temperature of the drive roller 107e and the conveyor belt 108, effectively preventing conveyor belt aging and deformation caused by excessive temperature. The lifting component 104 can flexibly adjust the height of the conveyor belt 108 according to different operating scenarios and material conveying requirements, ensuring smooth material conveying. The V-groove design on the surface of the conveyor belt 108 and the supporting and guiding function of the idler roller 109a prevent material slippage. The spiral heat dissipation fins 109b on the surface of the idler roller 109a in the auxiliary component 109 increase the heat dissipation area. The device is simple and efficient to operate, effectively solving the problems of traditional conveyor belts, drive rollers and conveyor belts generating a large amount of heat due to friction that is difficult to dissipate and the inability to adjust the conveyor belt angle.
